- W2025820718 abstract "Catalyst plays an important role in many of synthesis and chemical reactions, like α,β-unsaturated products cannot be synthesized without presence of suitable catalyst, but for efficient catalization of reactions catalyst must have high surface area as well as they must be easily removed after termination of reaction without leaving an impurity in final product. To achieve both of these conditions an innovative approach is used. Here Polycarbonate (PC)-ZnO NPs composites membranes have been successfully fabricated by solution casting technique in where ZnO NPs (45nm) acts as a catalyst with increased surface area, while as these catalyst are embedded in PC matrix that can be easily removed after termination of reaction. Membranes were characterized via different techniques like SEM, FTIR etc. Activity of this nanocomposite based catalytic system for the stereoselective synthesis of α, β-unsaturated compounds is tested and found increased in yield of compounds with increase in concentration of ZnO nanoparticle content upto 5%. Above this at high ZnO loadings (9%) slight agglomeration of NPs occurred which hindered the catalytic effect of Nano composite." @default.
